Question 1183404

Since this time Camy wants five-digit {{{even}}} integer, which means that the number "{{{4}}}" has to be at the unit digit and only {{{1}}}, {{{3}}}, {{{5}}}, {{{9 }}} can be moved freely.
 
There will be {{{4! = 24}}} times the {{{even}}} number {{{4}}} will be used (arrangements), so 

{{{4 * 24 = 96}}}

As for the remaining {{{4}}} numbers, their average (or mean) is {{{(1+3+5+9)/4=4.5}}}

then,  the sum of the integers on Camy's list is:
                               
{{{4.5 * ( 10000 + 1000 + 100 + 10) * 24   + 96 = 4.5 * 11110 * 24 + 96 = 1199976}}}
